Abstract (en)
[origin: EP1376066A2] An optical encoder (140, 350) includes a planar surface comprising an insulator material. An optical encoder pattern (630, 910) partially occupies the planar surface. The encoder pattern has at least one continuous geometry (620) and is made from a conductive material. <IMAGE>
